[PATCH 0/3] ARM: mstar: Add initial support for M5Stack UnitV2

[Daniel Palmer]

This series adds basic support for the soon to be released M5Stack
UnitV2 based on the SigmaStar SSD202D.

With the rest of the commits in my tree the SPI NAND, ethernet, USB etc
should work so the UnitV2 should be fully usable with a mainline-ish
kernel.

Hopefully this will encourage someone else to help with cleaning
up and pushing the commits for these SoCs.

[PATCH 1/3] dt-bindings: vendor-prefixes: Add vendor prefix for M5Stack

[Daniel Palmer]

M5Stack make various modules for STEM, Makers, IoT.
Their UnitV2 is based on a SigmaStar SSD202D SoC which
we already have some minimal support for so add a
prefix in preparation for UnitV2 board support.
